Internal SSL error with exchange 2007, extrenal works fine

Assuming the following.

WWW Domain: www.abc123.com
Interal Domain: abc
mail server: server1

Mail Server External: mail.abc123.com
Mail Server Internal: server1.abc123.com

So the SSL is registered to mail.abc123.com, works great both externally and internally when going to the OWA page, however internally, outlook is trying to access server1.abc123.com and gives me an SSL Mistmatch error everytime.

I dont know what to do to fix this, I have checked the forums, seems more people are having the opposite problem. Any help would be greatly appreciated.

If you want to use more than one name you'll need to define a SAN (Subject Alternative Name: http://en.wikipedia.org/wiki/Subject_Alternative_Name ) so that both names are valid for your certificate. Depending upon your Certificate Authority (VeriSign, Entrust, etc) how SAN names are issued, what type of certificate you may need and cost will vary.
Forgot to mention using a wild card certificate may be an option for you also. WildCard ssl certificates allow you to secure any subdomain of your domain.

I'm not sure if this would actually work but you could possibly use a CNAME dns record internally.

Akhater,

the second link: or if you prefer this script http://www.exchangeninjas.com/set-allvdirs

doesnt seem to work for me. Do I need to be registered on that site?
Create an A record on you internal DNS server to resolve to mail.abc123.com and this points to the Ip address of the CAS server. Ask internal user's to use the same URL to access OWA.

Owa works, even internal, its just outlook, it wants to grab the server name.
Hi,

No there is no need to register but it seems the site is down ...


I have a copy of the script I will attach it here, rename it to .ps1 and run it

set-allvdirs.txt

Eddie_86: Tried it after your post, really had high hopes, but now I have not only my original security error, now its saying it is expired... ugg

Akhater: I have your script, renamed it to .ps1 however its not runable, it just opens up in notepad. How do I run this?

And thank you

Any thoughts? I am also now getting a Cert Expired since I did the MS page that Edddie Suggested. Everything still works fine externally

Looks like everything works! So thank you! Only thing I had to do that i found somewhere else was to recycle the IIS Autodiscovery.

So thanks again!
